How to Clean an Air Filter on a Lawn Mower

If you’ve been noticing that your lawn mower isn’t running as smoothly as it used to, it might be time to check the air filter. Cleaning an air filter on a lawn mower is a simple process that can often restore its performance. With the right supplies and some basic know-how, you can get your lawn mower back in top running condition in no time!

Gathering Supplies

Maintaining a lawn mower is essential for keeping it running smoothly. The air filter plays an important part in this, as it keeps dirt and debris out of the engine. To ensure your machine runs efficiently, you’ll need to clean the air filter regularly. Gathering the right supplies is an important first step toward getting this task done quickly and easily.

You’ll need some basic tools such as pliers and a screwdriver. Additionally, you’ll want to get a replacement air filter if necessary, or make sure your existing one is in good shape. You’ll also need some cleaning materials like a brush and some mild detergent, as well as rags or paper towels for drying everything off when you’re finished. Finally, it’s also helpful to have a container of compressed air handy for blowing out any stubborn dirt or grime that won’t come off with just brushing and detergent. Once you have all these supplies ready, you can begin the task of cleaning your lawn mower’s air filter.

Removing the Air Filter

Start by locating the air filter – this can usually be found on the side of the engine near the carburetor. Once you’ve located it, carefully detach any clips or screws holding it in place using your pliers or screwdriver. Then, gently pull off the air filter cover, being careful not to break any plastic pieces in the process. After that, carefully pull out the old air filter and set aside for cleaning or replacement with a new one.

Cleaning the Air Filter

Keeping your lawn mower in good condition is essential for making sure it runs efficiently and properly. An important part of this maintenance is cleaning the air filter, which helps keep dirt, dust, and debris from entering the engine. To clean an air filter on a lawn mower, you will need a few simple tools and supplies.

Before beginning the cleaning process, it’s important to get the right tools and supplies together to make sure you’re able to do the job correctly. For this project, you’ll need a pair of needle-nose pliers or tweezers, a small brush or an old toothbrush, a container that can hold water or solvent cleaner (such as rubbing alcohol), and a rag or cloth.

Once you have everything gathered together that you need, it’s time to remove the air filter from the lawn mower. Depending on your model of lawn mower, you may need to remove a cover before being able to access the filter. Once everything is exposed and accessible, use your needle-nose pliers or tweezers to carefully remove the air filter from its area. It may be attached with metal clips or screws – use caution when removing these parts so you don’t damage them.

Now that your air filter is out of its housing unit, it’s time to start cleaning! Begin by using your brush or toothbrush to gently scrub away any dirt particles or debris from both sides of the filter. You may also use compressed air if necessary – just make sure not to blow too hard as this could damage some of the parts within your engine area. After brushing away all visible dirt particles from both sides of the filter, pour some water (or solvent cleaner) into your container and submerge the filter into it for about 10 minutes so any stubborn dirt particles can be removed easily.

Once 10 minutes has passed, take out your air filter and lay it down onto a dry rag or cloth so any remaining moisture can be absorbed completely before reinstalling it back into place in its housing unit on your lawn mower engine area. Make sure all surfaces are completely dry before putting your air filter back in – if moisture remains inside while running your lawn mower engine this could cause serious damage internally!

Reinstalling the Air Filter

Finishing the job is just as important as starting it! Reinstalling the air filter on a lawn mower is simple and straightforward. To begin, locate the appropriate mounting location for the air filter on your mower. This can be found in the owner’s manual of your particular model. Once you have determined where to install the filter, take the time to make sure that no debris has built up or fallen into this area while you were cleaning.

Line up the holes of your air filter with those of its mounting bracket, then press it firmly into place until it snaps securely into position. Now you are ready for a cleaner running engine and improved mowing performance! For added protection against dirt and dust buildup, consider applying some oil to the outside of your air filter before reinstalling. Doing so will help seal out any excess particles that may try to enter past any potential gaps in the mounting frame.


In conclusion, keeping your lawn mower’s air filter clean is essential for the health of your machine and the quality of your lawn. By gathering the supplies you need, removing the air filter carefully, giving it a good clean and then making sure to reinstall it correctly, you can make sure that your lawn mower will remain in good working order for years to come.
